EA won't run with real money

Then I ran the EA on two live demo accounts on VPS servers for 2 weeks and the results are good / in line with my expectations and the backtesting.

I decided to put real funds into one of these two brokers, and have setup and ran my EA in exactly the same way and with the same settings I have used for the last two weeks of live demo trading...but so far it isnt executing ...is there something I am missing an additional permission or the like?

‌T‌he only slight difference I can see is that my demo accounts were $10USD deposits, whereas this real account is £10k GBP and the contract size is 10000 whereas the demo was 100000. I am using code to adjust for account balance currency and contract size so I can't see this would make a difference.
